The vast majority of the time you will want to click the re-calibrate button
(the button that the advisory is pointing to)
Just click that button once:
And get back to shoooting!
One click is all it takes!
You DO NOT need to redraw your target zones, restart your camera, pause shooting, stand on your head, or anything else.
The lighting advisory can only be triggered by two things:
1.) The ambient light on the targets has changed enough to cause false hits.
This is by far the most common cause. LASR works by detecting differences in light levels, and when the ambient light levels change, you will need to re-calibrate sometimes. Often times, the lighting changes are subtle and over time, and you may not have noticed them. Again, one button click and get back to shooting.
2.) Unusually long laser impacts
If this is the case, you can ignore it and keep shooting. The lighting advisory does not interfere with shot detection or any other function of the software.
If the advisory comes up, and nothing seems to be wrong, i.e. no false hits and LASR is still detecting shots, you can also choose to ignore it, but be advised: LASR is warning you that your lighting conditions are changing enough to cause, or come very close to causing, false hits, and possibly stop shot detection all together.
